how bad was the mud in relation to what good mud is
Lord Josh when the Defoamer quits working that is some really gas-cut Bad Mud, chemicals being ineffective when added to gas-cut Bad Mud is the sign that Colloidal Forces have broken down. At least it came out today how overly gaseous the Macondo well was while drilling. There are tests to measure each of the five (5) Colloidal Forces but unfortunately I do not have them in my possession. Here the final draft of the above write-up submitted to the Senate Energy & Natural Resources Committee, hopefully they will be able to extract from BP such tests performed.
Annulus (oil well) – Wikipedia, the free encyclopedia
BP ran production casing into the gas-cut Drilling Mud and cemented with nitrified cement, a lightweight slurry, keeping the well from losing circulation. The pipe was hung-off with a casing hanger and cemented, and pipe weight set down the pack-off seal in the hanger assembly that sits in the casing head. The pack-off seal is for sealing-off the production casing from the surrounding string of pipe. BP tested their pack-off seal to 10,000 PSI pressure, from above the Annulus. Gas from the reservoir and gas-cut Bad Mud accumulated below the pack-off seal, about 17,000 feet above the cement in the Annulus, where Good Mud was supposed to be. In approximately 24 hours this accumulation exceeded the 10,000 PSI pressure tested, and the pack-off seal blew-out. Oil and gas had entered the Annulus through Bad Cement, and rose up the Annulus because of gas-cut Bad Mud, otherwise it would have stayed within the Bad Cement and oil reservoir. Similar circumstances surrounded the other eighteen (18) Gulf of Mexico ‘cementing’ blowouts, every one caused by gas-cut Bad Mud present in the wellbore, not the failure of tubulars or mechanical devices. They are only back-ups to the Right Mud, and the Good Mud, which should be in the hole, in the event Mud Engineers mixed the Wrong Mud, or the mud became gas-cut Bad Mud, such as the case here. Had they (BP, et al) chucked their gas-cut Bad Mud and replaced it with Good Mud before cementing, none of the eighteen (18) Gulf of Mexico blowouts would have occurred. This is good news for the offshore oil and gas industry, because the “Elementary” cause of these blowouts is now publically known.

Plug set inside the casing, if it were, would have no effect.

So the Engineers were right, gas-cut Bad Mud.
